Infill T3 more wiring

I have a question regarding the T3 wiring for output to an amp. You have RCA's marked for the front left and right. They work fine. There is another set labeld "Real Left" and "Real Right". I assume these were meant to say "Rear". They do not have any output however. I had to use a Y splitter to acheive 4 outputs. Now of course I have no abilty to control the "fade". Of course I can't find where to do this with SD anyhow.
